The tour was informative and interesting but there was quite a bit of walking as it was hard to get around a bus in the crowded streets within the timeframe. However, the website should advise the day Hagia Sophia is closed so tourists can decide whether they want to plan their trip around that day

This was a very memorable tour and it was really worth the trip. The Inca site was amazing! The only concern is the possibility of high altitude sickness in Cusco where you have to stay a night in order to make the trip the next day to Machu Picchu.
